What is “Remote Access”?
Remote access is the ability to get access to a computer or a network from a remote distance. Usually in corporations, people from branch offices or telecommuters may need access to the corporation’s network. Or some other employees need to use corporate data during their business trips. Even home users get access to the Internet through remote access to an Internet service provider (ISP). So you may already use it, but you do not know about it because it can appear in different places in different forms.
As mentioned above, one of the common methods of remote access is dial-up connection. Which use connection through desktop, notebook, or handheld computer modem over regular telephone lines.
The most common approach to this service is remote control of a computer by using another device. Seems like this procedure needs internet or any other network connection.
Here are the connection steps:
- First of all, user dials into a PC at the office.
- Then the office PC logs into a file server where the needed information is stored.
- And at the final step, the remote PC takes control of the office PC’s monitor and keyboard, allowing the remote user to view and manipulate information, execute commands, and exchange files.
Many computer manufacturers and large businesses’ help desks use this service widely for technical troubleshooting of their customers’ problems. Therefore you can find various professional first-party, third-party, open source, and freeware remote desktop applications. Which some of those are cross-platform across various versions of Windows, macOS, UNIX, and Linux. Remote desktop programs may include LogMeIn or TeamViewer.

Remote control is essentially a software solution. Note that remote control software require two computers to run the session: the remote system and the host system. So the remote system can be a branch office PC, a home PC, or a portable computer whose location changes daily. And the host system can be any computer attached to the LAN that is configured for remote access.
Remote Access Services (RAS)
First, Microsoft coined this term originally by referring to their built-in Windows NT remote access tools. RAS refers to any combination of hardware and software to enable the remote access tools or information that typically reside on a network of IT devices. Now we commonly use this service for online technical support for the personal or business computers rather than anything. The service includes support for dial up and logon, and also presents the same network interface as the normal network drivers.
Remote Access Server
Another popular subject is remote access server. Which is the name of the host computer that RAS connects a client to, it is also known as a communication server. It includes the computer and associated software that is set up to provide users remote access to network. These servers usually include a firewall server and a router. So the firewall server is used to ensure security. While the router can forward the access request remotely to another part of the corporate network.
